Advantages:
This system automation degree is high, the operation is simple, can complete the test through the software one key, automatically generate test curve, report;
The electric dynamometer can operate in four limits, either as a generator (load), or as a power machine (drive), positive and negative.
Energy saving: the output power of the motor is filtered by the frequency converter and energy feedback unit, and then returned to the grid and supplied to the tested motor.
Good stability of load control, constant speed or torque control, high control precision.
The system has high test precision, good repeatability and star farik.
Test most complete, the system can test the driver input voltage, current, power, drive output voltage, current, power and motor output torque, speed, power and the efficiency of the whole machine, drive efficiency, motor efficiency.
